GAGE-WHEEL FOR PLOWS.

SPECIFICATION forming part of Letters Patent No. 613,662, dated November8, 1898.

Application led August 30,1898.

To all whom it may concern,.-

Beit known that I, ANTON CARLSON, a citizen of the United States,residing at Pierce City, in the county of Lawrence and State ofMissouri, have invented a new and useful Gage-Wheel for Plows, of whichthe following is a specification.

My invention is an improvement in gagewheels for plows; and the objectis to provide an improved means by which the gage-wheel maybe easily andquickly raised by the driver without leaving his position at theplow-handles, so that when plowing washed-out ground or when the plowencounters obstructionssuch as stones, rocks, and stubble in the path vof the implementthe gage-wheel may be thrown out of service.

A further obj ect of the invention is to provide an improvedconstruction comprising a small number of parts each of a simple natureand united solidly together to producea substantial attachment which maybe easily applied to ordinary plows, and this attachment is guided toreduce the strain on the working parts and equipped with a latchmechanism adapted to hold the lever and gage-wheel in their adjustedpositions.

With these ends in view the invention consists in the novel constructionand arrangement of parts, which will be hereinafter fully described andclaimed.

To enable others to understand the invention, it is illustrated in theaccompanying drawings, forming a part of this specification, and inwhich- Figure 1 is a perspective view ofa plow with my improved gageattachment applied thereto. Fig. 2 is a plan view of the parts shown byFig. 1. Fig. 3 is a vertical crosssection on the plane indicated by thedotted line 3 3 of Fig. 2. Fig. 4. is a detail perspective view of thelever. Fig. 5 is a similar view of the guide-sector.

Like numerals of reference denote like and corresponding parts in eachof the several figures of the drawings.

In carrying my invention into practice I provide a main or operatinglever 10, which is cast in a single piece of metal in the form shownmore clearly by Fig. 4 of the drawings. At one end this lever'is formedwith an an- Serial No. 689,821. (No model.)

gular grip-piece 1l, and the other end of the lever has an integral arm14, which extends at an obtuse angle to the longitudinal axis of thelever. At the angle formed by the end of the lever and its arm 12 anotch 13 is formed in4 one face of the casting, and a simiwith anintegral lug 17, while the arm 16 has a similar lug 18. The sector andits arm are assembled in such relation tothe lever that the lugs 17 18will be received in the notches 14c 13, respectively, of the lever 10and its arm 12. This arrangement of the sector with relation to thelever brings the arm 16 in alinement longitudinally with the lever 10,While the free end of the sector is adapted for attachment tothe'corresponding end of the lever-arm 12. The sector and its arm arethus adapted for union with the lever and the arm 12 thereof bylapjoints, and said sector and the lever-arm are united lirmly togetherbya rivet or bolt 19, which passes through the notched end 14. of thearm and the lug 17 of the sector.

At the angle formed by the juncture of the sector and its arm there isprovided a short shaft or journal 20, on which is loosely mounted thegage-wheel 21, which may be of any preferred construction.

The lever is fulcrumed on one side of the plow-beam in a substantialmanner by a horizontal bolt 22, which passes through the lever at theangle of its arm 12 and also through the lug 18 of the sector-arm 16,thus confining the vsector-arm in the notched angle of the lever by thesame bolt which serves as the fulcrum for said lever. The fulcrum-bolt22 passes through the plowbeam to receive a nut or cap on its threadedprotruding end, and the headed end of the bolt bears against the exposed edge or face of the lever.

The lever and the attached sector are movable in a vertical plane on thehorizontal ful IOO crum-bolt 22, and this play of the lever and itssector is guided by a bolt which plays in a longitudinal slot 2G of thesector l5. The guide-bolt 27 has an enlarged head 28, that bears againstthe outside of the slotted sector, and this bolt is reduced to form theshoulder 29 and the stem 30. The shoulder of said bolt bears or abutsagainst the side of a plowbeam, While the stem passes through the beamto receive a nut 31, which may be tightened against the beam, so as todraw the shoulder 29 of the bolt firmly against one side of the beam,whereby the guide-bolt may be fastened firmly in place without causingthe head 2S thereof "to bind against the face of the guide-sector.

To hold the adjusting-lever and the gagewheel mounted on the sector intheir adjusted positions, I provide a locking-rack 32, which is cast ina single piece of metal to produce an arm 33 and a notched bar 34, andto provide for the proper application and secure attachment of thislocking-rack to a plowbeam the arm and bar are formed with the integralfoot-flanges 35, which are adapted to rest upon the plow-beam and to besecured firmly thereto by the vertical bolts 36. The locking-rack isfastened iirmly to the beam, so as to have its segmental notched bar 34concentric to the fulcrum-bolt 22, and on the swinging operating-leveris mounted a spring-controlled locking-bolt, which is adapted to engagewith the notched bar of the locking-rack to maintain the lever and thegage-wheel in either of their several positions. Secured rigidly to oneside of the lever, contiguous to the locking-rack, is the spring-housing37, which is provided with a forwardly-extended lip 38, that is adaptedto lap over and ride against one side of the notched segmental bar 34 ofthe locking rack, thus insuring the proper position of the lever and itshousing in relation to the locking-rack. Within this housing is aslidable bolt 39, which is normally pressed toward the rack by a spring40, and to the heel of this bolt is attached a pitman, cord, or wire 40,which extends along the lever to a handpiece 4l. This handpiece has thelugs 42 pivoted at 43 to the lever and its grip-piece ll, and saidhandpiece is thus mounted on the lever to provide a short arm 44,adapted to contact with the lever and to serve as a stop to limit themovement of the handpiece in relation to the grip ll of the lever.

In applying my attachment to a plow-beam the parts or members of suchattachment are assembled together and the fulcrum-bolt 22 is passedthrough the lever to pivotally mount the same on one side of the beam,thus providing a iirni support for the lever and the gage-wheel. Theguide-bolt is passed through the slot in the sector for its head toengage with said sector, while the stem of the bolt is attached firmlyto the beam. The lockingnut has its foot-flanges resting upon the beam,to which it is rmly secured by the vertical bolts, and the notched barof this rack is in a position for the spring-bolt to engage therewith.To raise the gage-wheel out of contact with the ground, the driveroperates the handpiece 4l to retract the bolt from the notched bar ofthe locking-rod, and then the lever is depressed to lift the segment andthe gagewheel, said segment traveling over the headed guide-bolt. Thegage-wheel may be lowered into position by reversing the movement of thelever, and the parts may be held firmly in their adjusted positions bythe latch-bolt engaging with the notched bar of the rack. The sectordirects the lever in its vertical adj ustment to insure accuracy ofpresentation of the gage-wheel to the ground and relieves thefulcrum-bolt of undue strain. The locking-rack occupies a compactposition on the beam, and it is of substantial construction, so that itwill withstand a great deal of strain. The entire device may be attachedeasily to any kind of a plow, and it is not liable to break or get outof order. The gage-wheel may be easily and quickly raised or loweredwithout requiring the driver to leave his station at the handles of theimplement. The attachment consists of a small number of parts which maybe readily assembled together to produce a substantial construction, andeach part is simple and cheaply cast in a single piece.

Changes may be made in the form of some of the parts while theiressential features are retained and the spirit of the inventionembodied. Hence I do not desire to be limited to the precise form of allthe parts as shown, reserving the right to vary therefrom.

Having thus described the invention, what I claim is- 1. In a gage-wheelattachment for plows, a lever provided with an angular arm and withnotches at the angular portion and at the free end of said arm, and aslotted guide-sector provided with an arm and with lugs at theextremities of said sector and its arm, said lugs adapted to it in thenotch of the lever and its arm to bring the arm of the sector inalinement with the lever, in combination with a gage-wheel journaled onthe sector, and a locking mechanism, substantially as described.
